This low-budget horror film from New Zealand is, for me, a textbook example of why I love the genre.

It has everything a quality horror movie needs, including the elements which big-budget and "typical American" horror all too often lack.

The film looks great, using the natural beauty of NZ alongside impressive cityscapes, but also showing us the very ordinary and (of course) the dark and ugly side of both the rural and urban environments.

The plot is straightforward but intelligently thought through and far from simple, resting on the characters and the tragic events in which they're embroiled.

There is violence and death, disturbing rather than gory, and an insidious tension which builds slowly and isn't allowed to dissipate until the very end.

The characters are sharply defined and individual, yet at the same time convincingly complex.

The dialogue is unpretty (sometimes even crude),but direct and often powerful - in many ways watching this was like discovering an unknown early Cronenberg flick, but in place of Cronenberg's cool intellectualism Garth Maxwell has crafted a highly emotional film which isn't afraid to take its viewers into uncomfortable territory.

Some of the performances might perhaps have been a little more fluid but Alexis Arquette (as the titular Jack) and especially Sarah Smuts-Kennedy as Dora are exceptionally honest in their portrayals of a damaged brother and sister. Mention must also be made of the blunt, persuasive presence of Bruno Lawrence, bringing to life a character who could easily have been badly mishandled.

Mainly, though, it's the ideas which make this shine. There are more surprises in this film than in the last dozen Hollywood horrors I watched... and thankfully they're the kind of surprised which make you think, not the kind which make you jump! There are very few FX beyond straight-up film techniques and a little fake blood, and that too is to the film's credit. This is a film about people whose lives have spiralled out of control and into the dark side, and while the paranormal elements are ever-present they're never the meat of the meal.

There are a few rough edges. As I mentioned in passing, the script has its clunky moments and not all the acting matches the quality of the standout roles. There were also some heavy-handed edits, and the sound design wasn't as accomplished as the visual aspects of the movie.

These are, however, minor quibbles, which didn't detract in the slightest from my enjoyment.

If you have an interest in the more sombre, conceptual side of the horror genre, this is an underrated modern classic, and comes highly recommended.

This fantastic film is an adventure based upon an old fairy tale with the stepmother and three gruesome step sisters. But Jack will be taking his bloody revenge.

Our film club featured this, and all the viewers were astonished. It's brutal, it's beautiful, it's sparkling with splatter and horror ideas. A true classic, and hidden gem! A complete movie of of vibrant colors sick ideas! The use of colors are greater than David Lynch manages in his films, and reminded me in that way of Blue Velvet!

You really don't know what you've been missing out before you see this! Go head over heels to get hold of this one! Though it deserves to be seen at a large screen, or preferably in a cinema, though that might be difficult for most.

This is one fine example of how great New Zealand cinema scene is, and I'll without any doubt consider this as a classic but refined gore, which should inspire many.

So get gold of this must-see film! But, of course... be nimble!

"Jack Be Nimble" is a strange and unpleasant movie, the result of an unsuccessful attempt to mix a whimsical gothic horror story with down-and-dirty social realism. The movie doesn't manage any atmosphere or scares and thus fails as horror, gothic or otherwise. Its attempts at realism also fail, with one-note performances and the constant incursion of the story's supernatural elements, which don't mesh with with the real locations and lack of style on offer.

The plot: a brother and sister are orphaned and split up when the sister is adopted first. She is adopted into a loving family, but the boy ends up being abused by sadistic foster parents, and spooked by their four daughters, who materialise over him and watch him sleep. He eventually escapes when he uses his mind control abilities with a machine he made in metal work to get his revenge, go off and find his sister. She shacks up with the legendary character actor Bruno Lawrence, in what I believe may have been his last film appearance. Their relationship - a young girl with a much older man - is too "real" for this material, like the theme of abusive foster parents. There are ways for supernatural fiction to deal with distressing, real-world issues, but this movie doesn't find them.

The main character is played by pre-surgery Alexis Arquette. I didn't realise he wasn't Kiwi, so he must have nailed the accent. He's kind of weird looking, though, like a Calvin Klein model with acromegaly. He reminds me of Rondo Hatton.

The movie was just such an awkward mix - and quite unpleasant in places - that I wasn't able to focus on it for long. It didn't make much sense and I don't think I wanted it to. I probably should have bailed out early.
